Abstract A self-propelled windrower has a traction unit with a fore-andaft body mounted on a pair of forward drive wheels and a pair of rearward caster wheels carried on an oscillating axle, the opposite drive and caster wheels being disposed outwardly of the opposite sides of the body. The oscillating axle is removable, and alternate mounting means are provided on the body for mounting the caster wheels directly to the body when the axle is removed. The windrower includes a removable transversely elongated header, and four windrowers and headers are mounted on a single flatcar in two sets. The axles and the headers are removed from the windrowers for shipping and the caster wheels are positioned in their alternate mounting on the body. The traction units are positioned on the railroad car in a fore-andaft direction, with the rearward end of the windrowers in each set opposite one another with the two headers for the two traction units disposed longitudinally on opposite sides of the traction unit bodies, the headers being disposed in a fore-andaft direction between the fore-and-aft aligned drive wheels of the opposite traction units.
In a self-propelled vehicle having a body partly supported on a pair of forward drive wheels and including a pair of side frame members mounted on opposite sides of the body and a rear transverse frame member connecting the rearward ends of the side frame members, the improvement comprising: a longitudinal pivot means mounted on the rearward end of the body; a transverse rear axle structure removable mounted on the pivot means so as to pivot about an axis extending in the direction of motion of said vehicle; a first pair of vertical socket means respectively mounted on the opposite ends of the rear axle structure; a second pair of vertical socket means respectively mounted on opposite sides of the body adjacent the opposite side frame members and adjacent the rear frame member, inwardly and forwardly of the first pair of socket means, and a pair of caster wheel structures respectively having vertical pivot elements rotatably and removably mountable in the first or the second socket means, the caster wheels being mounted in the first pair of socket means when the axle structure is mounted on the vehicle and being mounted in the second pair of socket means when the axle structure is removed.
